Sunlight Photosynthesis: 6CO 2 + H 2 6 H 12 O 6 + 6O 2 In the above reaction, sunlight supplies the energy to convert carbon dioxide and water to glucose and oxygen.Hydrothermal vents, which are hot springs on the sea floor, support exotic chemical-based ecosys-tems.
At first glance, the animals inhabiting deep-sea hydrothermal vents may not seem so dissimilar to other deep-sea creatures. But in fact, they are unlike any other life on Earth. Instead of sunlight, vent life relies on hydrogen sulfide-more commonly known as rotten egg gas and toxic to most land-based life.ntil recently, all life on Earth was believed to be dependent on the sun.

Deep-sea hydrothermal vents form as a result of volcanic activity on the ocean floor.
